Intricately branched, prickly shrub 0.5–1.5 m tall, terminal branches relatively undivided. Bark grey. Stipules evident below phyllode clusters, 2–3 mm long, slender, rigid, , shallowly recurved, pungent but normally brittle in upper ½ with commonly only basal portion persisting at mature nodes. Phyllodes in often short-nodose fascicles of 4–10 (–12), oblong to elliptic or obovate, (1.5–) 2–3 mm long, 0.6–1 mm wide, obtuse and innocuous, straight, slightly thickened, glabrous; nerves not visible or midrib very obscure; pulvinus distinct, 0.3–0.5 mm long; gland absent. Inflorescences simple; peduncles 4–10 mm long, slender, glabrous to sparsely hairy; heads globular, small (c. 4 mm diam.), 17–20 flowered, bright yellow. Flowers 5-merous; sepals free, linear-spathulate. Pods sub-moniliform, clearly raised over seeds and shallowly constricted between them, 20–50 mm long, 3–3.5 mm wide, thinly coriaceous, mostly strongly curved (sometimes into an open circle), curved/twisted or coiled upon dehiscence, light brown. Seed small (2.5–3.5 mm long), very dark brown to black; aril partially sheathing base of seed.
